Jörg Schlatterer, Postdoc at the Albert Einstein College of Medicine in New York, suggests to found an International Postdoc Forum (IPF). Though I just escaped the postdoctoral life, I am totally in favor of this idea - just that it seems to me like I've heard similar suggestions several times before and nothing ever came out of it. There would definitely be a huge benefit from an international association of postdocs that could provide e.g. advice on national differences and difficulties with settling in a foreign country, fractured retirement options and absence of unemployment insurance. One of the problems is if you're not in your home country you have no voice neither at home (because hey, you left, now good luck) nor in the new country (because hey, you work here but please don't have an opinion).Together with a colleague Schlatterer wrote a brief article for the newsletter of above mentioned US Postdoc Association:

"Although many characteristics of postdoctoral research positions vary between disciplines, institutions, and nations, some challenges are universal. Poorly defined roles and responsibilities, unstable and uncompetitive salaries, lack of benefits, variable mentorship quality, and access to courses and career development programs are common complaints. It is important to consider how research communities around the world can meet these challenges, and what an International Forum for Postdocs (IFP) might contribute."

It is however very hard to get academics to organize in any way. They are typically primarily work-oriented and community involvement that isn't CV suitable is distraction and a waste of time. In any case, I wish the IPF good luck.

ΛCDM has more issues than the finetuning of the CC, see eg this paper. There's definitely something lacking in our understanding of the universe, and dark matter along won't help. Either way, the emphasis of my paper isn't so much on the bi-metric, but on the exchange symmetry. Best,

Since gravity is mediated by a spin-2 field, like charges attract and unlike charges repel | The introduction of the second connection suffices to describe the motion of anti-gravitating test-particles in a background field.

Big Bang the universe into a soup of g- and h-metric particles with only gravitational interaction between them. Does h-metric matter cool, photon emission or otherwise?

Unless there is a robust asymmetry in effective mass or abundance, h-metric particles cannot be excluded - there is nowhere for them to disappear (extruded into another set of dimension?). Gravitational effects would be reciprocal, g- and h-metric particles, yes?

The h-particles behave exactly as the usual ones. In the simplest case, there's an h-parter for every g-particle, a funny electron, a funny photon, a funny swhatever. The h-matter couples only graviationally to usual matter, thus it doesn't emit photons, it emits h-photons.

Michael: I had to delete your comment. It was off-topic and contained a link with the only purpose to advertise your site. Please do not repeat that. It is pointless, I will delete all similar attempts. This blog is to discuss solely what is in our posts. Best,
